本文中编译的工具都会放到$LFS/tools

基本过程基本都是

• 解压
• configure
• make
• make install
• 删除解压文件

binutls

查看/mnt/lfs/sources下的压缩包

lfs:/mnt/lfs/sources$ ls | grep binutils
binutils-2.38-lto_fix-1.patch
binutils-2.38.tar.xz

解压

lfs:/mnt/lfs/sources$ tar -xf binutils-2.38.tar.xz
lfs:/mnt/lfs/sources$ ls | grep binutils
binutils-2.38
binutils-2.38-lto_fix-1.patch
binutils-2.38.tar.xz

创建build目录

lfs:/mnt/lfs/sources$ cd binutils-2.38
lfs:/mnt/lfs/sources/binutils-2.38$ mkdir -v build
mkdir: created directory 'build'

lfs:/mnt/lfs/sources/binutils-2.38$ cd build
lfs:/mnt/lfs/sources/binutils-2.38/build$

configure

lfs:/mnt/lfs/sources/binutils-2.38/build$ ../configure --prefix=$LFS/tools \

configure: creating ./config.status
config.status: creating Makefile


lfs:/mnt/lfs/sources/binutils-2.38/build$ ls
Makefile  config.log  config.status  serdep.tmp

接下来进行编译和安装

lfs:/mnt/lfs/sources/binutils-2.38/build$make
lfs:/mnt/lfs/sources/binutils-2.38/build$make install
lfs:/mnt/lfs/sources/binutils-2.38/build$ ls
Makefile  binutils    config.status  gas    intl  libctf     opcodes     zlib
bfd   config.log  etc        gprof  ld    libiberty  serdep.tmp

完成后，去sources文件夹下把解压的binutils文件夹删掉

lfs:/mnt/lfs/sources$ ls | grep binut
binutils-2.38
binutils-2.38-lto_fix-1.patch
binutils-2.38.tar.xz
lfs:/mnt/lfs/sources$ rm -rf binutils-2.38
lfs:/mnt/lfs/sources$ ls | grep binut
binutils-2.38-lto_fix-1.patch
binutils-2.38.tar.xz

GCC

解压

lfs:/mnt/lfs/sources$ ls | grep gcc
gcc-11.2.0.tar.xz
lfs:/mnt/lfs/sources$ tar -xf gcc-11.2.0.tar.xz
lfs:/mnt/lfs/sources$ ls | grep gcc
gcc-11.2.0
gcc-11.2.0.tar.xz

将GMP, MPFR and MPC packages 放入gcc

lfs:/mnt/lfs/sources$ cd gcc-11.2.0
lfs:/mnt/lfs/sources/gcc-11.2.0$ tar -xf ../mpfr-4.1.0.tar.xz
lfs:/mnt/lfs/sources/gcc-11.2.0$ mv -v mpfr-4.1.0 mpfr

lfs:/mnt/lfs/sources/gcc-11.2.0$ mv -v gmp-6.2.1 gmp
'gmp-6.2.1' -> 'gmp'
lfs:/mnt/lfs/sources/gcc-11.2.0$ tar -xf ../mpc-1.2.1.tar.gz
lfs:/mnt/lfs/sources/gcc-11.2.0$ mv -v mpc-1.2.1 mpc
'mpc-1.2.1' -> 'mpc'

case $(uname -m) in

    sed -e '/m64=/s/lib64/lib/' \

遇到报错，这里是机器资源不足，我把MAKEFLAG 中-j4 删掉，重新make就成功了
